A Macomb Township woman accused of biting off a portion of her boyfriend’s left ear was charged Monday with felonious assault.

Danielle Nebelung, 31, was held on $10,000 cash or surety bond following her arraignment in 41A District Court on one count of aggravated assault, police said.

Macomb County Sheriff’s officials reported that the 36-year-old victim claimed Nebelung, his live-in girlfriend, arrived at their home early Saturday morning in the 49000 block of Marseilles and they began arguing.

As the man tried to walk into a bedroom, she followed and began punching him in the head, the Sheriff’s Office reported. When the man turned his back to her, she jumped on his back and bit the ear, severing a substantial portion, Lt. John Michalke said.

The victim was treated by paramedics and taken to a local hospital where the portion of the severed ear also was brought.

Sheriff’s deputies arrested the suspected girlfriend at the home, which is located near 22 Mile Road, east of Romeo Plank.

Police did not reveal the reason for the argument that turned physical.

Nebelung is scheduled to return to court for a preliminary hearing March 17.
